Using Bounds Based upon Correctness

In Jay’s recent webinars 4 & 5, we looked at student responses and how to change visibility based upon current or prior responses.
We mainly looked at correctness indicators and using variables and restrictions to determine when items are visible.

I’m wondering about using bounds. If we setup an activity like the attached sample, are there any downsides? (things that would “break” this plan or make it ineffective)?

screen 1: there’s a button you need to press.
screen 2: the bounds and therefore visibility is controlled based upon whether or not you pressed the button on screen1.

Screen 1, you didn’t press the button --> screen 2, you have a strange bound off to the side and see the lock image.
Screen 1, you DID press the button --> screen 2, you have a regular bound and can see the graph that you need for whatever is required on screen 2.

Sample activity:

Screen2: CL

Screen 2: graph

Prior to this approach, we noticed the following facts:

  1. If the image is at the BOTTOM of the graph list, then it would appear OVER most other items? (not sure if this is correct? it appears over function graphs and inequality shading.)
  2. The image appears BEHIND points (regardless of where in the list).

SO, if you don’t do bounds, the webinar had a variable to create correct versus not correct. If correct, then show points. If not correct, then show image. So you’d have to program several things in graph accordingly.
Anyways, to keep things simpler for basic users that don’t understand piecewise and restrictions as well, I’m wondering if the bounds approach might be a viable option.
Apologies this is long. Hoping it helps know where our thoughts came from :wink:

Fun approach! love it.
